Never look for keyholes in the dark again with this glow-in-the-dark touchpad lockset that locks or unlocks your door's deadbolt lock when you enter a customized code. This convenient touchpad system is similar to high-security applications found in office buildings and institutional facilities, yet can be easily installed at home by anyone who knows how to use a screwdriver. No drilling and no running of power cords is required for this Touchpad Lockset Deadbolt with brass finish. The unit uses 4 AA batteries (sold separately), which provide enough power for 18,000 successful activations. You set the entry codes yourself — the only people that will know the codes are the ones you give it to. Codes can be anywhere from 2 to 8 digits. You can program as many as six different entry codes, each of which can be added or deleted individually. This feature makes it easy to enter temporary codes for houseguests, maids or repairmen. Programming is a simple push-button process, and takes only minutes. The deadbolt is incredibly secure, built with a 6-pin, solid brass cylinder and a gear with clutch drive system to prevent wear-out. And don't even think about anyone trying to figure out your code — the door lock sounds a warning alarm after four failed attempts. Two conventional keys are included for standard operation. The Touchpad Lockset Deadbolt is also available in nickel finish, antique brass and oiled bronze.
